before setting this to "need more info" I have experienced a similar issue when open 2.82-2.83 files with 2.9 series.

(on windows 10)
The first time when i open a 2.82-3 file it will displayed like this

If you had it opened once no additional geometrie will be displayed.

Also some files wont open if you doulble click on them BUT they can be opened from blender within. or the other way round.

Is this releated to the issue or should this go in a seperate Ticket?

Oh @MarcinTwarowski & @Jewls Visually, It seems the same... One difference perhaps: the strange geometry never appear when the viewport is in solid mode display :) (eevee)

Those reported bugs are all Windows and Nvidia, you have Linux and AMD. So they might be not related.

I had this issue happen too, but can't replicate this issue on the latest build of 2.91 (21fec95139), can you try with this build and see if it works?

Thx @MarcinTwarowski keeping an eye on the duplicate reports.
Since #77910 is the oldest (and @fclem is already involved there), lets keep that report as the central place to investigate this further (so will merge these reports...)
